STEAM-CONDENSER.

To all whom it may concern:

Be it known that I, PRESTON H. SELLERS, a citizen of the United States,and resident of East St. Louis, Illinois, have invented certain new anduseful Improvements in Steam-Condensers, of which the following is aspecification, containing a full, clear, and exact description,reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in a steam condenser for whichLetters Patent were granted to me November 6, 1906 and numbered 835,260.

The object of my present invention is to construct a condenser having aseries of baffle plates on the interior thereof arranged to cause thesteam admitted thereto to travel in a tortuous path through thecondenser, which baffle plates are provided with hinged lower ends.

A further object of my present invention is to construct a steamcondenser having a removable head which, together with the baffle plateshaving hinged ends, provides means whereby access may be had to any partof the condenser for purposes of cleaning or repair.

A further object of my present invention is to construct a devicecarried by the watersupply pipe for directing the water therefrom toeither side of the condenser, and a still further object of my inventionis to construct a novel means for leveling the water-supply pipe, whichmeans are secured to the heads of the condenser where there is littledanger of their being broken in shiping. p For the above purposes myinvention consists in certain novel features of construc tion andarrangement of parts as will be hereinafter more fully described,pointed out in the claims and illustrated by the ac companying drawing,in which:

Figure l is an elevation of the complete condensing apparatus, thewater-supply pipe and condenser being shown partly in section; Fig. 2 isan enlarged, vertical, transverse, sectional elevation taken on the line22 of Fig. 1; Fig. 3 is a left hand end elevation of the completecondenser; and, Fig. 4L is an enlarged, detail, vertical, sectionalelevation taken on the line H of Fig. 1.

Referring by numerals to the accompanying drawing: 1 designates the bodyportion Specification of Letters Patent.

of my improved condenser which is constructed of suitable sheet metalsuch as 'alvanized iron and is in the form of an e ongated tank, theside walls of which are riveted together at their upper edges, whichside walls extend from a point where they are joined downwardly andoutwardly on slight angles and the bottom 2 of the body is rounded.

8 designates a fixed head at one end of the condenser and a a removablehead at the op posite end of the condenser, the end of the condenser towhich the removable head 1 is secured is provided with a perforatedflange 5 and bolts 6 are inserted through said head and flanges forremovably securing the head to said flanges. Extending through the head3 is a steam inlet-pipe 7 and leading from the bottom of the tank,adjacent the head 4, is an outlet-pipe 8. Each of the heads 3 and i isprovided with openings into which are seated pipes 9 provided withvalves 10, which pipes and valves are arranged to be operated for thepurpose of withdrawing non-condensible gases and vapors from thecondenser.

Positioned within the tank, equi-distant apart, is a number of battleplates 11 and 12. To the lower end of each of the baitle plates ishinged a door 13 and secured within the tank, parallel with the door andbaffle plates, is a number of angle plates 14 against which the doorsabut when in closed positions, and carried by each door is a pair ofthumb screws 15 arranged for engagement with said angle plates forlocking the doors in closed positions.

The battle plates 11 are of less height than the baifle plates 12 asrequired to cause steam to travel in a tortuous path through thecondenser.

Each of the hinged doors 13 is provided with an opening 16, the openingsin the doors secured to the battle plates 12 being larger than theopenings in the doors hinged to the baflie plates 11.

Commencing with the right hand or initial compartment of the condenser,by reason of the restricted opening between the top of the initialbaffle plate and top of the tank, the major portion of the steamadmitted to said compartment is directed in a course under the battleplate through an opening in the hinged door, then, by reason of therestricted opening in the second hinged door,

the steam is directed in a course above said I second baflie plate. Inthis manner the steam is caused to travel over a number of the baffleplates and under the remaining bafiie plates, and the steam whichcondenses between each pair of battle plates is directed through theopenings in the hinged doors to the pipe 8.

Positioned longitudinally of the tank at its apex is a slotted waterpipe 17, which pipe is preferably made in two sections, the outer endsof each section being closed by a cap 18.

17 is caused to flow down in equal amounts over each side of thecondensing tank.

Heretofore, the water flowing from the pipes 17 was affected by windswhich caused the water to flow unevenly over the surfaces of the tank,and by the employment of my improved spreader there is an equal amountof water over the entire surface of the tank.

In my former patent, there was no means which provided access to thetank for purposes of cleaning and repair. In the present construction ofthe tank the removable head and hinged doors of the baffle plates,provide access to any part of the tank.

I claim:

1. In a steam condenser of the class described, an inverted V-shapedtank having a rounded bottom, a removable head for said tank, baflieplates of unequal lengths vertlcally disposed at intervals within andthroughout the length of the tank, the battle plates of greatest lengthextending to the apex of the tank and the bafiie plates of lesser lengthterminating some distance be low said apex, a hinged door carried byeach baflie plate, there being an opening in each of the doors, theopenings in the doors carried by the battle plates of greatest lengthbeing larger than the openings in the remaining doors.

2. In a steam condenser of the class described, an inverted V-shapedtank having a rounded bottom, a removable head for said tank, bailieplates arranged at intervals Secured to the united ends of the tank, adjacent the longitudinal center of the tank,is an internally threadedpipe-union 19 having integral, perforated ears 20 which are secured tothe united ends of the tank and, sup ported by the pipe-union is anopen-topped bowl 21 which communicates with the union 19. The pipes 17are threaded at their inner ends, which threaded ends are seated in theunion l9.

Secured to each head of the tank is a bracket 22, and carried by each ofsaid brackets is a threaded stem 23 having an integral ring 24 throughwhich the pipes 17 are passed to be supported. Embracing the stem 23 isa pair of nuts 25, one on either side of the horizontal portion of thebracket 22 to provide for the vertical adjustment of the outer ends ofthe pipe 17 for purposes of leveling the pipes. Inverted V shaped Jspreaders 26, the apexes of which contact] with the pipes 17, are hungfrom the pipes throughout the length of the tank, each al- 17 by thestraps 27 which embrace the pipes ternate bafile plate extending to theapex of 17. Arranged to discharge water into the, the tank, theremaining baflie plates terbowl 21 is a water-supply pipe 28, and 10-minating a distance below the apex, a door,

cated in said pipe is a valve 29. Secured to the sides of the tank 1 area number of supporting brackets 30 arranged to be employed l in securingthe condenser in position for use. In practical use steam to becondensed is introduced to the tank through the inlet 7 and, as beforestated, by reason of the peculiar arrangement of the baffle plates,travels having an opening therethrough, hinged to each baflie plate,means for locking the doors in planes paralleling the baffle plates, theopenings in the doors being of different sizes and the doors beingalternately arranged according to the sizes of the openings.

In testimony whereof, I have signed my name to this specification, inpresence of two in a tortuous path through the condenser. subscribingwitnesses.

The valve 29 in the waterpipe is then opened and Water is supplied tothe bowl 21 PRESTON SELLERS and pipes 17 and discharges through theVitnesses:
